Blumenstein Castle is a castle ruin in the Palatinate Forest probably constructed in the first half of the 13th century as part of a line of defensive castles along the Alsatian border. The castle was first mentioned in 1332 in connection with knight Anselm from Batzendorf near Blumenstein. After a feud with the House of Fleckenstein in 1347, the knight was banished from the castle.
About 1350, the counts of Zweibrücken had one quarter of the castle, the House of Dahn owned the rest. Blumenstein castle was probably destroyed in the German Peasants' War in 1525. The ruin passed from the counts of Hanau-Lichtenberg to the landgraves of Hesse, then to the bishopric of Speyer and finally to the state of Rheinland-Pfalz.
References:The ancient Argos Theater was built in 320 BC. and is located in Argos, Greece against Larissa Hill. Nearby from this site is Agora, Roman Odeon, and the Baths of Argos. The theater is one of the largest architectural developments in Greece and was renovated in ca 120 AD.
The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
